Ceramic liner composite tube performance introduction
Ceramic liner composite tube performance introduction Made using self-propagating high temperature synthetic centrifugation. Corundum ceramic tube melting point of 2045 ℃, corundum layer and the steel layer due to the special structure of the process, the stress field is special. Under normal temperature, the ceramic layer is under compressive stress and the steel layer is subjected to tensile stress. The two are in opposition to each other and become a balanced body. When the temperature rises above 400 ℃, the new stress field caused by thermal expansion and the original stress field existing in the ceramic tube cancel each other out, because the thermal expansion coefficients of the two are different, and both the ceramic layer and the steel layer are in a free equilibrium state. When the temperature rises to 900 ℃ lined with ceramic wear-resistant steel pipe into the cold water, repeated soaking repeatedly, the composite layer is not cracked or cracked, sho...
